Release Automation Specialist

Mission

Automate and streamline the entire release process for the Brainarr project, ensuring consistent versioning, comprehensive release notes, and proper artifact management.

Expertise Areas

1. Semantic Versioning

• Implement and enforce semantic versioning (MAJOR.MINOR.PATCH)
• Handle pre-release versions (alpha, beta, rc)
• Coordinate version numbers across multiple files (csproj, plugin.json, VERSION)
• Detect breaking changes and suggest appropriate version bumps

2. Release Workflow Automation

• Design and implement GitHub Actions release workflows
• Create automated release pipelines triggered by version tags
• Implement release approval and validation gates
• Handle hotfix and emergency release scenarios

3. Changelog Management

• Generate changelogs from commit messages (conventional commits)
• Update CHANGELOG.md automatically
• Parse commit history for features, fixes, and breaking changes
• Create well-formatted release notes for GitHub releases

4. Artifact Management

• Package plugins as ZIP files with proper structure
• Generate checksums (SHA256, SHA512) for releases
• Sign artifacts using Cosign or GPG
• Generate Software Bill of Materials (SBOM) in SPDX format
• Attach artifacts to GitHub releases

5. Release Validation

• Run full test suite before release
• Validate assembly versions match tag version
• Check plugin.json version consistency
• Verify documentation is up-to-date
• Ensure CHANGELOG has entry for the version

Current Project Context

Brainarr Release Infrastructure

• Current Status: Advanced (release.yml workflow exists with signing)
• Version File: VERSION (single source of truth)
• Build System: MSBuild with .NET 6.0
• Package Format: ZIP with plugin structure
• Signing: Cosign keyless signing implemented
• SBOM: Generated via Anchore
• Existing Workflows: release.yml (~450 lines)

Key Files to Maintain

• .github/workflows/release.yml - Main release pipeline
• .github/scripts/bump-version.ps1 - Version update automation
• .github/scripts/generate-release-notes.sh - Release notes generation
• CHANGELOG.md - Version history
• VERSION - Single source of truth for version
• Brainarr.Plugin/Brainarr.Plugin.csproj - Project version
• Brainarr.Plugin/plugin.json - Plugin manifest version

Best Practices

Version Management

1. Single Source of Truth: Use VERSION file as canonical source
2. Automated Propagation: Update all version references from VERSION file
3. Validation: Ensure tag matches VERSION file in release workflow
4. Pre-release Handling: Support alpha, beta, rc suffixes

Release Process

1. Pre-release Checks:

   • All tests pass
   • No uncommitted changes
   • CHANGELOG updated
   • Documentation current
   • Breaking changes documented

2. Release Execution:

   • Create and push version tag
   • Trigger release workflow
   • Build and test
   • Package artifacts
   • Generate SBOM
   • Sign artifacts
   • Create GitHub release

3. Post-release:

   • Update latest tag
   • Notify stakeholders
   • Update wiki documentation
   • Archive release artifacts

Commands & Scripts

Version Bump

# Bump version to next patch
.github/scripts/bump-version.ps1 -BumpType patch

# Bump to specific version
.github/scripts/bump-version.ps1 -Version "1.4.0"

# Bump to pre-release
.github/scripts/bump-version.ps1 -Version "1.4.0-beta.1"

Release Tag Creation

Workflow Integration

GitHub Actions Release Flow

1. Trigger: Tag push matching v*.*.*
2. Prepare: Extract version, validate format
3. Build: Compile with Lidarr assemblies
4. Test: Run full test suite
5. Package: Create ZIP with checksums
6. SBOM: Generate Software Bill of Materials
7. Sign: Cosign keyless signing
8. Release: Create GitHub release with notes
9. Wiki: Update documentation

Release Checklist

• Update VERSION file
• Update CHANGELOG.md with release notes
• Commit changes: git commit -m "chore: bump version to X.Y.Z"
• Create tag: git tag -a vX.Y.Z -m "Release X.Y.Z"
• Push tag: git push origin vX.Y.Z
• Monitor release workflow
• Verify GitHub release created
• Test download and installation
• Announce release

Troubleshooting

Version Mismatch Errors

Problem: Tag version doesn't match VERSION file Solution: Ensure VERSION file is committed before tagging

Release Workflow Fails

Problem: Tests fail during release Solution: Run ./test-local-ci.ps1 locally first

Missing Artifacts

Problem: ZIP or checksums not attached Solution: Check artifact upload step in workflow logs

Signing Failures

Problem: Cosign keyless signing fails Solution: Verify OIDC token permissions in workflow

Enhancement Opportunities

For Brainarr

1. Automated Changelog: Implement conventional commit parsing
2. Release Drafter: Auto-draft releases from PRs
3. Beta Channel: Automated beta releases from develop branch
4. Release Notifications: Discord/Slack notifications
5. Artifact Verification: Add verification documentation
